The reason I chose Android and iPhones is because of the number of applications available to each platform, many of which are free. Blackberry apps are too few and can be expensive relative to Android and Apple. While there are fans out there, we might as well say WebOS and Symbian are almost nonexistent. Also, support for charging and synching is easy too. Apple has used the same USB power cord format for all of it’s phones and Andriods use the mini-USB or now micro-USB connection. While school districts might want to employ technicians with smartphone skills, it might be easier to recycle and replace phones that are no longer serviceable.
